Hydrotechnik UK Ltd is one of the UK’s leading test and measurement equipment distributors and manufacturers, servicing a wide range of industries since 1990.
A hydraulic accumulator is a pressure storage reservoir in which a non-compressible hydraulic fluid is held under pressure by an external source. The external source can be a spring, a raised weight, or a compressed gas. An accumulator enables a hydraulic system to cope with extremes of demand using a less powerful pump, to respond more quickly to a temporary demand, and to smooth out pulsations.
A compressed gas accumulator consists of a cylinder with two chambers that are separated by an elastic diaphragm, a totally enclosed bladder, or a floating piston. One chamber contains hydraulic fluid and is connected to the hydraulic line. The other chamber contains an inert gas under pressure (typically nitrogen) that provides the compressive force on the hydraulic fluid. As the volume of the compressed gas changes, the pressure of the gas (and the pressure on the fluid) changes inversely.
Wind turbines commonly use piston type accumulators because of their smaller footprint and high pressure performance and are commonly fitted with Minimess charging valves due to their high pressure capability, leak-free design and safe ease of use.
Hydrotechnik have developed a range of nitrogen gas charging and testing kits specifically for the wind generation market and for general hydraulic applications.
The kits all utilise their leak-free Minimess gas charging valves. The kits have adaptors to suit almost all modern accumulator designs even when Minimess is not fitted. Microbore hoses are supplied for easy connection & purging before charging under high pressure. Their flexibility, anti-leak design and small bore provides a controlled charging process. Hydrotechnik equipment is chosen for it’s rugged high quality, ease of use and flexibility and is the choice of industry professionals worldwide.

Minimess™ primary charging connectionAll Hydrotechnik’s Accumulator charging connections are based around Hydrotechnik’s Minimess leak proof gas charging valves which are widely adopted and allow an operator to connect and disconnect under full system pressure without the loss of gas or pressure. Suitable up to 630 bar, Minimess® charging and testing valves are a dual purpose device with a reliable safe screwed connection, they allow for safe charging and discharging of gas.

Safe, easy to use, diverse, leak-free and long lasting.
Hydrotechnik manufacture a range of high quality gas charging valves and testing points for use with most gases in the Minimess® 1215, 1615 & 1620 series design. Our Minimess gas charging valves are manufactured with very precise internal tolerances to give maximum sealing integrity, not possible with standard Minimess test points. Manufactured in Brass, 1.4571 (316Ti) or 1.4104 stainless steel grades with special compound Viton or Buna Nitrile sealing gives high performance in the harshest of environments.
